    The plasma arc welding machines plasmaweld 202 and 402 have been developed for welding with transferred arc, i. E. The main arc transfers from the tungsten to the work piece. These units can also be used for tig, tig pilot arc and manual metal arc (mma) welding. The power supplies can be used in con...
